Protein energy wasting in children with chronic kidney disease: is lean body mass by DEXA a key diagnostic biomarker?

The article focuses on evaluating a new scoring system for diagnosing protein energy wasting (PEW) in children with chronic kidney disease (CKD), particularly emphasizing the importance of lean body mass (LBM) measured by dual-energy x-ray absorptiometry (DEXA) as diagnostic biomarker. Topics include the criteria and biomarkers for diagnosing PEW, the utility of LBM measurement by DEXA in detecting subclinical PEW, and considerations regarding the limitations and practicality of using DEXA.
